Resolver without gyroscope is meaningless.  And gyro without resolver is also meaningless.  In order to determine whether a deviation from the target angle has occurred, we need a  fixed point for the measurement.  The fixed point can only be a gyro.  Because the gyro does not move while turret or gun swing.

 

A rate (gyro) sensor is usually a gyro with 2 degrees of freedom + resolver as signal transducer.

There are devices that can replace gyroscopes.

The new Russian stabilizer 2E58 should use FASER rate gyros. With LASER or FASER gyros, there is actually no start delay.

Just found in my archive:

Introduction to the M1 Abrams Tank: Armament

 

Task 4. Describe the components of the gun/turret drive and stabilizing systems

...

2. Gun/Turret.  Drive and Stabilization Systems

...

a. Azimut Channel

...

(1) Gyros. Azimut stabilization signals ar obtained from two gyros: the hull gyro and the azimut  axis of the sight gyro. The hull gyro provides the information nessecary to maintain  the turret stabilization when the hull moves beneath the turret. The azimut gyro ist located in the LOS head assembly. It reports any azimut motion in the turret and thereby refines the correction in azimuth.

...

b. Elevation Channel

...

(1)  Operation. ... The sight gyroscope senses movement of the sight head mirror and sends the sight elevation to the LOS electronic unit. This keeps the head mirror steady while the M1 and the sight move up and dow.

...

And, yes, each gyro is connected to a resolver to send a signal corresponding angle and angel velocity.
